If you use the TARBS box you can only get ONE transponder at a time, its not like a Nokia or A humax where you can add heaps of different freq/s/r/fec, the TARBS box is classified as a DTH box you put the home freq in and the rest tag along, same as Foxtel and Austar. On Nss6 if you want to get the both "X" TARBS transponders you must use another Digital FTA box say I use a Nokia I have over 100 different sets Of Freq/S/R and FEC's.<br />Enjoy while it last, I will find out more info within the next week or two regarding the "X" channels on NSS6 and Thaicom.
